Let's simplify step-by-step. 7−4(3−(4y−5))

Distribute: =7+(−4)(3)+(−4)(−4y)+(−4)(5)=7+−12+16y+−20

Combine Like Terms: =7+−12+16y+−20=(16y)+(7+−12+−20)=16y+−25

Answer: =16y−25

7 - 4[3 - (4y - 5)]
= 7 - 4[3 - 4y + 5]
= 7 - 4[-4y + 3 + 5]
= 7 - 4[-4y + 8]
= 7 + 4*4y - 4*8
= 7 + 16y - 32
= 16y - 32 + 7
= 16y - 25

HELPPO ME PLEASEE!!!!!!

Answer:

Here,

x + 25° + 3x + 95° + 80°=360° (Sum of angles of a quadrilateral is 360°)

or,x+3x + 25° + 95° + 80° =360°

or,4x + 200 = 360°

or,4x = 360 - 200

or,4x = 160

or,x = 160÷4

or,x = 40

Now,

Angle K = (x + 25)° = 40 + 25° = 65°

Angle L = 3x° = 3 × 40° = 120°
